using the mid.jar MANIFEST.MF build details to get the actual ServiceNow version?

[stevemac]

Hi,

We face a challenge with instance upgrades (full and patch) and our CyberArk (CP) integrations.  The CyberArk Hash value for mid.jar changes with each version.

We have semi-automated the generation of the Hash value as follows:

• Download the new version of the MID Server Agent zip file from install.service-now.com to the MID Server host (using the build date and tag information)
• Extract the contents of the zip file into a temporary directory
• from the instance (via a custom widget and using a custom flow / powershell), execute the Cyberark Hash utility against extracted mid.jar file
  • this will return the hash value and get the package.filename value from agent\packaage\meta\mid-core.meta.properties

I'd like to get to the stage where we only extract the mid.jar file and determine the ServiceNow version from mid.jar.   The issue is I cannot  find the "friendly" ServiceNow version from the mid.var file.  I can get the build info from the manifest file, but have no idea how to get the ServiceNow version from that

• Is anyone aware how to use the MANIFEST.MF (\agent\lib\mid.jar\META-INF\) information in the JAR file to get the ServiceNow version?
• is there anything else in mid.jar that can be used to get the version?

thanks,

Steve

Thanks for this.  I was aware of these files.   I am trying to determine the version from mid.jar.  It changes in each release (which causes the CyberArk utility to generate a different Hash value).   

Hoping anyone with knowledge of mid.jar or any ServiceNow API  / lookup for mid.jar build details would chime in if possible (or impossible)

I'm not really following so might be it's not helpful but you can get a handful of information from instanceinfo.do and xmlstats.do. 

fetch("https://<>.service-now.com/InstanceInfo.do?SOAP", {
